WisdomTree Continuous Commodity Index Fund

WisdomTree Continuous Commodity Index Master Fund

Table of Contents

PART I

WisdomTree Continuous Commodity Index Fund (the “Fund”) and WisdomTree Continuous Commodity Index Master Fund (the “Master Fund” and together with the Fund, the “Funds”) are commodity pools that were organized as Delaware statutory trusts on October 27, 2006. WisdomTree Commodity Services, LLC serves as the commodity pool operator and managing owner (the “Managing Owner”) of the Funds, and GreenHaven Advisors LLC serves as the commodity tradingadvisor (the “Sub-Adviser”).

The Fund continuously offers shares representing common units of fractional undivided beneficial interest in and ownership of the Fund (“Shares”). Upon inception of the Fund, the Fund issued 50 of its general units to the Managing Owner in exchange for a capital contribution of $1,500.

The Fund invests substantially all of its assets in the Master Fund in a master-feeder structure. The Master Fund is wholly-owned by the Fund and the Managing Owner. The Master Fund and the Fund each follow the same investment objective. The Fund holds no investment assets other than the Master Fund’s common units of beneficial interest (“Master Fund Units”). Upon inception of the Master Fund, the Master Fund issued 50 of its general units to the Managing Owner in exchange for a capital contribution of $1,500. Each Share issued by the Fund correlates to a Master Fund Unit held by the Fund.

The principal executive offices of the Funds and the Managing Owner are located at 245 Park Avenue, 35th Floor, New York, New York 10167,telephone (866) 909-9473. The Managing Owner currently maintains an Internet website at www.wisdomtree.com, through which the Funds’ annual, quarterly and periodic reports filed with or furnished to the Securities and Exchange Commission (the “SEC”) pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended (“Exchange Act”), are made available free of charge. Additional information regarding the Funds may also be found on the SEC’s EDGAR database at www.sec.gov.

Investment Objective

The Funds’ investment objective is to provide investors with exposure to the daily change in the price of a portfolio of commodities (the “Index Commodities”) comprising the Thomson Reuters Continuous Commodity Index (the “Index”), before Fund liabilities and expenses. The Index Commodities consist of corn, soybeans, wheat, live cattle, lean hogs, gold, silver, copper, cocoa, coffee, sugar, cotton, soybean oil, platinum, crude oil, NY Harbor ULSD (formerly known as heating oil), and natural gas.

The Fund pursues its investment objective by investing substantially all of its assets in the Master Fund. The Master Fund pursues its investment objective by actively trading exchange traded futures (“Commodity Futures”) on the Index Commodities, with a view to tracking the performance of the Index over time, regardless of whether the Index is rising, falling or flat over any particular period. The Master Fund’snon-discretionary investment strategy is designed to provide investors with a cost-effective and convenient way to invest in an equal-weight portfolio of Commodity Futures.

The Master Fund’s portfolio (the “Portfolio”) also includes cash, U.S. Treasury obligations and other high credit-quality, short-term fixed income securities (collectively, “U.S. Treasuries”) for deposit with the Fund’s commodity broker as margin or otherwise held to cover the Master Fund’s notional exposure to Commodity Futures.

An investment in the Shares is:

There can be no assurance that the Funds will achieve their investment objective or avoid substantial losses. The value of the Shares is expected to fluctuate generally in relation to changes in the value of the Master Fund Units.

The Index

Thomson Reuters (Markets) LLC, formerly Thomson Reuters America LLC (the “Index Sponsor”), is the owner, publisher and calculation agent of the Index (sometimes referred to as the “Continuous Commodity Total Return Index” or “Equal Weight Continuous Commodity Total Return Index”) (for purposes of this section, also referred to as the“CCI-TR”). The Index Sponsor is not an affiliate of the Funds or the Managing Owner.

TheCCI-TR is an equal weighted index of 17 commodities. It is a “total return” version of the Thomson Reuters Continuous Commodity Index (the “CCI”) because it includes a “roll yield” and adds the yield of3-month U.S. Treasury bills to the return. Due to its equal weighting, theCCI-TR offers significant exposure to grains, livestock and soft commodities, and a lower energy weighting than many of its peers.

The CCI is an iteration of the original Commodity Research Bureau Index, which is currently known as the Thomson Reuters/CoreCommodity CRB Index (the “CRB Index”). The original CRB Index was widely viewed as a broad measure of overall commodity price trends because of the diverse nature of its constituent commodities. In 2005, the CRB Index was revised for a ninth time, and that ninth version was named the Continuous Commodity Index. On January 7, 2013, the CCI was revised to include CME Soybean oil and remove ICE Frozen Concentrated Orange Juice at an equivalent allocation.

The base year for theCCI-TR is 1982, with a starting value of 100. The base year of the CCI is 1967 with a starting value of 100. The CCI andCCI-TR are materially different from the CRB Index.

Each of the CCI and theCCI-TR reflects the price movement of 17 exchange-traded Commodity Futures: corn, soybeans, wheat, live cattle, lean hogs, gold, silver, copper, cocoa, coffee, sugar, cotton, soybean oil, platinum, crude oil, NY Harbor ULSD (formerly known as heating oil) and natural gas.

TheCCI-TR aims to represent the return that an investor should expect to receive if such investor were to attempt to replicate the CCI (by buying the applicable Commodity Futures and collateralizing the investment with U.S. Treasuries). TheCCI-TR takes into account the economics of rolling listed Commodity Futures forward to avoid delivery and maintain exposure in liquid contracts. TheCCI-TR is notionally composed of Commodity Futures on the physical Index Commodities. Unlike equities, which typically entitle the holder to a continuing stake in a corporation, Commodity Futures normally specify a certain date for the delivery of the underlying physical commodity. To avoid the delivery process and maintain a long futures position, contracts nearing a delivery date must be sold and contracts that have not yet reached delivery must be purchased. This process is known as “rolling” a futures position. An index, such as theCCI-TR, is commonly known as a “rolling index” because it replaces futures contracts as they approach maturity by notionally selling and purchasing offsetting contracts to avoid delivery and maintain exposure in liquid contracts.

Index Methodology

The individual commodity contributions are calculated as follows:

where,

C_m,t stands for the sum across the included contracts for each of the 17 commodities, so

[For example: Corn sum (as of 1/7/17) = (3/17 price + 5/17 price + 7/17 price) / 33]

avgt

stands for the daily average of settlement prices

The CRBCC defines the actively considered set of futures contracts for each commodity as defined further in the 6 roll schedules listed in the appendix.

Note: that for example after a weekend, 3 days of returns are due to be added to the Index.

Contract Roll

The roll periods take place during the week leading up to the second Friday of the same six months (Jan, Feb, Apr, June, Aug, and Nov) every year. The roll implies a change from thepre-roll basket of contracts to the post-roll basket according to the following pattern:

CCI Total Return Historical Prices (Monthly)

Tabular Performance

TheCCI-TR is an equal weight commodity index. By its very structure an evenly-weighted index will provide broader exposure than one that is not evenly-weighted. To the extent that an index is over-weighted in a particular commodity class, such as energy, that index will reflect the energy sector more than it will the broad commodity universe. The table below indicates the constituent commodities, their index weighting and the sector weighting within the Index.

Interruption of Index Calculation

Calculation of theCCI-TR may not be possible or feasible under certain events or circumstances, including, without limitation, a systems failure, natural orman-made disaster, act of God, armed conflict, act of terrorism, riot or labor disruption or any similar intervening circumstance, that is beyond the reasonable control of Thomson Reuters, the Managing Owner or theSub-Adviser. Additionally, calculation of theCCI-TR may also be disrupted by an event that would require Thomson Reuters to calculate the closing price in respect of the relevant commodity on an alternative basis.

Investments; Margin

The Fund uses a substantial portion of the proceeds from the sale to investors of baskets (“Baskets”) of 50,000 Shares to purchase Master Fund Units. The Master Fund uses substantially all of the proceeds it receives from the sale of its Master Fund Units to actively trade exchange-traded Commodity Futures on the Index Commodities, based on the Funds’ investment objective of tracking the performance of the Index over time, less the expenses of the operations of the Funds. The Master Fund’s Portfolio also includes cash, U.S. Treasury obligations and other high credit-quality, short-term fixed income securities for deposit with the Commodity Broker (as defined below) as margin or otherwise held to cover the Master Fund’s notional exposure to Commodity Futures.

All proceeds received from the sale of Baskets are used to achieve the Funds’ investment objective and to pay certain fees and expenses of the Funds.

When the Master Fund trades in Commodity Futures on U.S. exchanges, it is required to deposit a portion of the value of the contract or other interest as security to ensure payment for the underlying obligation. This deposit is known as initial margin. The assets deposited by the Master Fund with its Commodity Broker as margin must be segregated pursuant to the regulations of the U.S. Commodity Futures Trading Commission (the “CFTC”). Such segregated funds may be invested only in a limited range of instruments.

Although the percentages set forth below may vary substantially over time, as of the date of this Annual Report, the Master Fund estimates:

TheSub-Adviser, a registered commodity trading advisor, is responsible for the cash management activities of the Master Fund, including investing in U.S. Treasuries.

The Master Fund receives 100% of the interest income earned on its interest income assets.

Net Asset Value; Indicative Fund Value

“Net Asset Value” means the total assets of the Master Fund including, but not limited to, all cash and cash equivalents or other debt securities, less total liabilities of the Master Fund, each determined on the basis of generally accepted accounting principles in the U.S., consistently applied under the accrual method of accounting. In particular, Net Asset Value includes any unrealized profit or loss on open Commodity Futures, and any other credit or debit accruing to the Master Fund but unpaid or not received by the Master Fund. All open Commodity Futures traded on a U.S. exchange will be calculated at their then current market value, which will be based upon the settlement price for that particular Commodity Future traded on the applicable U.S. exchange on the date with respect to which Net Asset Value is being determined; provided, that if a Commodity Future traded on a U.S. exchange could not be liquidated on such day, due to the operation of daily limits or other rules of the exchange upon which that position is traded or otherwise, the settlement price on the most recent day on which the position could have been liquidated shall be the basis for determining the market value of such position for such day.

The current market value of all open Commodity Futures traded on anon-U.S. exchange shall be based upon the settlement price for that particular commodity futures contract traded on the applicablenon-U.S. exchange on the date with respect to which Net Asset Value is being determined; provided, that if a Commodity Future traded on anon-U.S. exchange could not be liquidated on such day, due to the operation of daily limits (if applicable) or other rules of the exchange upon which that position is traded or otherwise, the settlement price on the most recent day on which the position could have been liquidated shall be the basis for determining the market value of such position for such day.

The Managing Owner may in its discretion (and under extraordinary circumstances, including, but not limited to, periods during which a settlement price of a Commodity Future is not available due to exchange limit orders or force majeure type events such as systems failure, natural orman-made disaster, act of God, armed conflict, act of terrorism, riot or labor disruption or any similar intervening circumstance) value any asset of the Master Fund pursuant to such other principles as the Managing Owner deems fair and equitable so long as such principles are consistent with normal industry standards. Notwithstanding the foregoing, such valuations may differ from valuations of others in the industry. Interest earned on the Master Fund’s commodity brokerage account will be accrued at least monthly. The amount of any distribution will be a liability of the Master Fund from the day when the distribution is declared until it is paid. Because there will be aone-to-one correlation between Shares and Master Fund Units, the Net Asset Value per Share and the Net Asset Value per Master Fund Unit will be equal.

The Fund’s Administrator (as defined below) calculates the Net Asset Value once each NYSE Arca trading day. The Net Asset Value for a particular trading day is released after 5:00 p.m. ET and posted at www.wisdomtree.com.

To provide updated information relating to the Fund for use by investors and market professionals, the NYSE Arca calculates and disseminates throughout the trading day an updated “indicative fund value.” The indicative fund value is calculated by using the prior day’s closing Net Asset Value per Master Fund Unit as a base and updating that value throughout the trading day to reflect changes in the value of the Master Fund’s Commodity Futures during the trading day. Changes in the value of U.S. Treasuries will not be included in the calculation of indicative fund value. The indicative fund value will be disseminated on a per Share basis every 15 seconds during regular NYSE Arca trading hours of 9:30 a.m. ET to 4:00 p.m. ET.

Creation and Redemption of Shares

The Fund creates and redeems Shares from time to time, but only in one or more Baskets of 50,000 Shares. Authorized Participants are the only persons that may place orders to create and redeem Baskets. Each “Authorized Participant” must (i) be a registered broker-dealer or other securities market participant, such as a bank or other financial institution that is not required to register as a broker-dealer to engage in securities transactions, (ii) be a participant in the Depository Trust Company (“DTC”), and (iii) have entered into a “Participant Agreement.” A list of the current Authorized Participants can be obtained from the Managing Owner. Investors not qualified as Authorized Participants will not be able to place orders to create and redeem Baskets directly from the Fund. However, Authorized Participants may sell the Shares included in the Baskets they purchase from the Fund to other investors.

The Participant Agreement sets forth the procedures for the creation and redemption of Baskets and for the payment of cash required for such creations and redemptions. Under the Participant Agreement, the Managing Owner has agreed to indemnify an Authorized Participant against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “1933 Act”). Authorized Participants are cautioned that some of their activities may result in their being deemed participants in a distribution in a manner that would render them statutory underwriters and subject them to the prospectus delivery and liability provisions of the 1933 Act.

Authorized Participants may act for their own accounts or as agents for broker-dealers, custodians and other securities market participants that wish to create or redeem Baskets.

The times for creation and redemption ordercut-off times and/or settlement set forth below are as of the date of this Annual Report and may be revised as designated by the Fund or its agents on the order form or related procedures as communicated to Authorized Participants.

Creation Procedures

General. On any business day, an Authorized Participant may place an order with the Fund’s Distributor (as defined below) (as facilitated by the Fund’s Administrator) to create one or more Baskets. For purposes of processing both purchase and redemption orders, a “business day” means any day other than a day when banks in New York City are required or permitted to be closed. Purchase orders must be placed by 10:00 a.m. ET. The day on which a valid purchase order is received is the purchase order date. Purchase orders are irrevocable. By placing a purchase order, and prior to delivery of such Baskets, an Authorized Participant’s DTC account will be charged thenon-refundable transaction fee due for the purchase order.

Determination of Required Payment. The total payment required to create each Basket is the Net Asset Value of 50,000 Shares as of the closing time of NYSE Arca or the last to close of the exchanges on which the Index Commodities are traded, whichever is later, on the purchase order date. Baskets will be issued as of 12:00 p.m. ET, on the business day immediately following the purchase order date at the Net Asset Value per Share as of the closing time of NYSE Arca or the last to close of the exchanges on which the Index Commodities are traded, whichever is later, on the purchase order date during the continuous offering period, but only if the required payment has been timely received.

Because orders to purchase Baskets must be placed by 10:00 a.m. ET, but the total payment required to create a Basket during the continuous offering period will not be determined until 4:00 p.m. ET, on the date the purchase order is received, Authorized Participants will not know the total amount of the payment required to create a Basket at the time they submit an irrevocable purchase order for the Basket. The Fund’s Net Asset Value and the total amount of the payment required to create a Basket could rise or fall substantially between the time an irrevocable purchase order is submitted and the time the amount of the purchase price in respect thereof is determined.

Rejection of Purchase Orders. The Administrator may reject a purchase order if:

The Distributor and the Managing Owner will not be liable for the rejection of any purchase order.

Redemption Procedures

General. The procedures by which an Authorized Participant can redeem one or more Baskets mirror the procedures for the creation of Baskets. On any business day, an Authorized Participant may place an order with the Distributor (as facilitated by the Administrator) to redeem one or more Baskets. Redemption orders must be placed by 10:00 a.m. ET. The day on which a valid redemption order is received in proper form is the redemption order date. Redemption orders are irrevocable. Individual Shareholders may not redeem directly from the Fund.

By placing a redemption order, an Authorized Participant agrees to deliver the Baskets to be redeemed through DTC’s book-entry system to the Fund not later than 12:00 p.m. ET, on the business day immediately following the redemption order date. By placing a redemption order, and prior to receipt of the redemption proceeds, an Authorized Participant’s DTC account will be charged thenon-refundable transaction fee due for the redemption order.

Determination of Required Payment. The redemption proceeds from the Fund consist of the cash redemption amount equal to the Net Asset Value of the number of Basket(s) requested in the Authorized Participant’s redemption order as of the closing time of the NYSE Arca or the last to close of the exchanges on which the Index Commodities are traded, whichever is later, on the redemption order date. The Managing Owner will distribute the cash redemption amount at 12:00 p.m. ET, on the business day immediately following the redemption order date through DTC to the account of the Authorized Participant as recorded on DTC’s book entry system.

Delivery of Redemption Proceeds. The redemption proceeds due from the Fund are delivered to the Authorized Participant at 12:00 p.m. ET, on the business day immediately following the redemption order date if, by such time, the Fund’s DTC account has been credited with the Baskets to be redeemed. If the Fund’s DTC account has not been credited with all of the Baskets to be redeemed by such time, the redemption distribution is delivered to the extent of whole Baskets received. Any remainder of the redemption distribution is delivered on the next business day to the extent of remaining whole Baskets received if the Distributor receives the fee applicable to the extension of the redemption distribution date which the Distributor may, fromtime-to-time, determine and the remaining Baskets to be redeemed are credited to the Fund’s DTC account by 12:00 p.m. ET, on such next business day. Any further outstanding amount of the redemption order shall be cancelled. The Distributor is also authorized to deliver the redemption distribution notwithstanding that the Baskets to be redeemed are not credited to the Fund’s DTC account by 12:00 p.m. ET, on the business day immediately following the redemption order date if the Authorized Participant has collateralized its obligation to deliver the Baskets through DTC’s book entry system on such terms as the Distributor and the Managing Owner may fromtime-to-time agree upon.

Suspension or Rejection of Redemption Orders. The Managing Owner may suspend the right of redemption, or postpone the redemption settlement date, (1) for any period during which an emergency exists as a result of which the redemption distribution is not reasonably practicable, or (2) for such other period as the Managing Owner determines to be necessary for the protection of the Shareholders. The Managing Owner will not be liable to any person or in any way for any loss or damages that may result from any such suspension or postponement.

A redemption order may be rejected if the order is not in proper form as described in the order form and/or Participant Agreement or if the fulfillment of the order, in the opinion of its counsel, might be unlawful.

Creation and Redemption Transaction Fee. To compensate State Street Bank and Trust Company (referred to herein as “State Street” or the “Administrator” ),), as Administrator of the Funds, for services in processing the creation and redemption of Baskets, an Authorized Participant is required to pay a transaction fee to the Fund of $200 per order to create or redeem Baskets. An order may include multiple Baskets. The transaction fee may be reduced, increased or otherwise changed by State Street with consent from the Managing Owner. State Street must notify DTC of any agreement to change the transaction fee and will not implement any increase in the fee for the redemption of Baskets until thirty (30) days after the date of the notice.

The times for creation and redemptionorder cut-off times and/or settlement set forth above may be revised as designated by the Funds or its agents on the order form or related procedures as communicated to Authorized Participants.

Secondary Market Trading

The Net Asset Value per Share will change as fluctuations occur in the market value of the Portfolio. The public trading price per Share may be different from the Net Asset Value per Share. Consequently, an Authorized Participant may be able to create or redeem a Basket at a discount or a premium to the public trading price per Share. This price difference may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for Shares is closely related, but not identical, to the same forces influencing the price of the underlying commodity at any point in time.

Advisors and Associated Persons

The Trustee

Delaware Trust Company, a Delaware corporation, is the sole Trustee of the Funds (the “Trustee”). The Trustee’s principal offices are located at 2711 Centerville Road, Suite 210, Wilmington, DE 19808. The Trustee is unaffiliated with the Managing Owner.

Under the Declaration of Trust and Trust Agreement, dated as of October 27, 2006 and as amended January 4, 2016, of the Fund, (the “Fund Trust Agreement”) and the Declaration of Trust and Trust Agreement, dated as of October 27, 2006 and as amended July 29, 2007 and January 4, 2016, of the Master Fund (the “Master Fund Trust Agreement” and collectively with the Fund Trust Agreement, the “Trust Agreements”), the Trustee has delegated to the Managing Owner the exclusive management and control of all aspects of the business of the Funds.

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.

The Trustee has no duty or liability to supervise or monitor the performance of the Managing Owner, nor does the Trustee have any liability for the acts or omissions of the Managing Owner.

The Trustee is permitted to resign upon at least sixty (60) days’ notice to the Fund or the Master Fund, as applicable; provided, that any such resignation will not be effective until a successor Trustee is appointed by the Managing Owner. The Trust Agreements of each of the Funds provides that the Trustee is compensated by the Fund or the Master Fund, as applicable, and is indemnified by the Fund or Master Fund, as applicable, against any expenses it incurs relating to or arising out of the formation, operation or termination of the Fund or Master Fund, as applicable, or the performance of its duties pursuant to the applicable Trust Agreement, except to the extent that such expenses result from the gross negligence or willful misconduct of the Trustee.

In its capacity as Distributor, FFS assists the Managing Owner and the Administrator with certain functions and duties relating to the creation and redemption of Baskets, including assisting in matters associated with receiving and processing orders from Authorized Participants to create and redeem Baskets, coordinating the processing of such orders and related functions and duties. The Distributor does not open or maintain customer accounts or handle orders for the Funds.

FFS may be contacted at Foreside Fund Services LLC, Three Canal Plaza, Suite 100, Portland, Maine 04101. Investors may obtain information regarding the Distributor by calling toll-free in the U.S. at (866)909-9473.

Fees and Expenses

Organization and Offering

The Managing Owner and its predecessor have paid and will pay the fees and expenses incurred in connection with the formation, qualification and registration of the Funds and the Shares under applicable U.S. federal and state law, and any other expenses actually incurred and, directly or indirectly, related to the organization of the Funds or the offering of the Shares prior to the time such Shares begin trading or in subsequent offerings, including but not limited to, expenses such as:

The Managing Owner is not reimbursed in connection with the payment of the organizational and offering expenses of the Funds.

Ordinary Fees and Expenses

The Managing Owner pays the following ongoing administrative fees and expenses incurred by the Funds:

The Managing Owner will not be reimbursed in connection with the payment of all routine operational, administrative and other ordinary expenses of the Funds.

The Funds pay the following ongoing administrative fees and expenses incurred by the Funds:

Extraordinary Fees and Expenses

The Funds payspay all of the Funds’ extraordinary fees and expenses generally, if any, as determined by the Managing Owner. Extraordinary fees and expenses are likely to includenon-recurring fees such as legal claims and liabilities, litigation costs and any permitted indemnification payments related thereto, if any, but the Managing Owner has discretion to treat other unanticipated expenses as extraordinary fees and expenses. Routine operational, administrative and other ordinary fees and expenses will not be deemed extraordinary fees and expenses.

Upfront Selling Commissions

No upfront selling commissions will be charged to Shareholders, although investors are expected to be charged a customary commission by their brokers in connection with purchases of Shares that will vary from investor to investor. Investors are encouraged to review the terms of their brokerage accounts for details on applicable charges.

Fee Table

The following table describes the Funds’ estimated fees and compensation arrangements with the Managing Owner, the Trustee and certain othernon-affiliated service providers. Asset-based fees are calculated on a daily basis (accrued at 1/365 of the applicable percentage of Net Asset Value on that day) and paid on a monthly basis. The Management Fee and other fees and expenses payable by the Funds will be paid first out of interest income from the Funds’ holdings of U.S. Treasuries. It is expected that, at current interest rates, such interest income will be sufficient to cover all or a significant portion of the Management Fee and other fees and expenses payable by the Funds.

Governance; Shareholder Rights and Protections

Duties of the Managing Owner

As managing owner of the Funds, the Managing Owner effectively is subject to the duties and restrictions imposed on “fiduciaries” under both statutory and common law. The Managing Owner has a fiduciary responsibility to the Shareholders to exercise good faith, fairness and loyalty in all dealings affecting the Funds, consistent with the terms of the Trust Agreements. The general fiduciary duties which would otherwise be imposed on the Managing Owner (which would make the operation of the Funds as described herein impracticable due to the strict prohibition imposed by such duties on, for example, conflicts of interest on behalf of a fiduciary in its dealings with its beneficiaries), are defined and limited in scope by the disclosure of the business terms of the Funds, as set forth herein and in the Trust Agreements (to which terms all Shareholders, by subscribing to the Shares, are deemed to consent).

The Trust Agreements provide that the Managing Owner and its affiliates shall have no liability to the Funds or to any Shareholder for any loss suffered by the Funds arising out of any action or inaction of the Managing Owner or its affiliates or their respective directors, officers, shareholders, partners, members, managers or employees (the “Managing Owner Indemnified Parties”), if the Managing Owner Indemnified Parties, in good faith, determined that such course of conduct was in the best interests of the Funds, and such course of conduct did not constitute gross negligence or willful misconduct by the Managing Owner Indemnified Parties. The Funds will indemnify the Managing Owner Indemnified Parties against claims, losses or liabilities based on their conduct relating to the applicable Fund, provided that the conduct resulting in the claims, losses or liabilities for which indemnity is sought did not constitute gross negligence or willful misconduct and was done in good faith and in a manner reasonably believed to be in the best interests of the applicable Fund.

In addition, the Trust Agreements specifically do not impose any general fiduciary duties on the Managing Owner. Under the Delaware Statutory Trust Act and the governing documents of the Managing Owner, the sole member of the Managing Owner, WisdomTree Investments, Inc., is not responsible for the debts, obligations and liabilities of the Managing Owner solely by reason of being the sole member of the Managing Owner.

Under Delaware law, a beneficial owner of a statutory trust (such as a Shareholder) may, under certain circumstances and in accordance with the statutory trust’s governing instrument, institute legal action on behalf of himself and all other similarly situated beneficial owners (a “class action”) to recover damages from a managing owner of such statutory trust for violations of fiduciary duties, or on behalf of a statutory trust (a “derivative action”) to recover damages from a third party where a trustee with authority to do so has failed or refused to institute proceedings to recover such damages. In addition, beneficial owners may have the right, subject to certain legal requirements, to bring class actions in federal court to enforce their rights under the federal securities laws and the rules and regulations promulgated thereunder by the SEC. Beneficial owners who have suffered losses in connection with the purchase or sale of their beneficial interests may be able to recover such losses from a managing owner where the losses result from a violation by the managing owner of the anti-fraud provisions of the federal securities laws.

Management; Voting by Shareholders

The Shareholders take no part in the management or control, and have no voice in the operations or the business of the Funds.

The Managing Owner has the right unilaterally to amend the Trust Agreements; provided that the Shareholders have the right to vote only if expressly required under Delaware or federal law or rules or regulations of the NYSE Arca or other applicable national securities exchange, or if submitted to the Shareholders by the Managing Owner in its sole discretion. No amendment affecting the Trustee shall be binding upon or effective against the Trustee unless consented to by the Trustee in writing.

The Shareholders may also amend the Trust Agreement of the Fund, except in certain limited respects, by the affirmative vote of the Shares then owned by Shareholders representing a majority of the Net Asset Value (excluding any Shares held by the Managing Owner and its affiliates). The affirmative vote of the Shares then owned by Shareholders representing at least 75% of the Net Asset Value may also compel dissolution of the Fund. The owners of 10% of the outstanding Shares then owned by Shareholders have the right to bring a matter before a vote of the Shareholders. The Managing Owner has no power under the Fund’s Trust Agreement to restrict any of the Shareholders’ voting rights. Any Shares purchased by the Managing Owner or its affiliates, as well as the Managing Owner’s general interest in the Funds, arenon-voting.

Recognition of the Funds in Certain States

A number of states do not have “business trust” statutes such as that under which the Funds have been formed in the State of Delaware. It is possible, although unlikely, that a court in such a state could hold that, due to the absence of any statutory provision to the contrary in such jurisdiction, the Shareholders, although entitled under Delaware law to the same limitation on personal liability as stockholders in a private corporation for profit organized under the laws of the State of Delaware, are not so entitled in such state. To

protect the Funds’ shareholders against any loss of limited liability, the Trust Agreements provide that no written obligation may be undertaken by the applicable Fund unless such obligation is explicitly limited so as not to be enforceable against any shareholder personally. Furthermore, each of the Funds themselves indemnify all shareholders against any liability that such shareholders might incur in addition to that of a beneficial owner. The Managing Owner will use its assets to satisfy any such liability before such liability would be enforced against any Fund shareholder individually.

Possible Repayment of Distributions Received by Shareholders; Indemnification by Shareholders

The Shares are limited liability investments, and investors may not lose more than the amount that they invest plus any profits recognized on their investment. However, Shareholders could be required, as a matter of bankruptcy law, to return to the estate of the Fund any distribution received at a time when the Fund was in fact insolvent or in violation of its Trust Agreement. In addition, although the Managing Owner is not aware of this provision ever having been invoked in the case of any public futures fund, Shareholders agree in the Trust Agreement that they will indemnify the Fund for any harm suffered by it as a result of (i) Shareholders’ actions unrelated to the business of the Fund, or (ii) taxes imposed on the Shares by the states or municipalities in which such investors reside.

The foregoing repayment of distributions and indemnity provisions (other than the provision for Shareholders indemnifying the Fund for taxes imposed upon it by the state or municipality in which particular Shareholders reside, which is included to address the unlikely possibility that the tax status of the Fund is challenged in a state with a business trust statute) are commonplace in statutory trusts and limited partnerships.

Shares; Certificates

Individual certificates are not issued for the Shares. Instead, global certificates are deposited by the Trustee with DTC and registered in the name of Cede & Co., as nominee for DTC. The global certificates evidence all of the Shares outstanding at any time. Under the Fund Trust Agreement, Shareholders are limited to (1) participants in DTC such as banks, brokers, dealers and trust companies (“DTC Participants”), (2) those who maintain, either directly or indirectly, a custodial relationship with a DTC Participant (Indirect Participants), and (3) those banks, brokers, dealers, trust companies and others who hold interests in the Shares through DTC Participants or Indirect Participants. The Shares are only transferable through the book-entry system of DTC. Shareholders who are not DTC Participants may transfer their Shares through DTC by instructing the DTC Participant holding their Shares (or by instructing the Indirect Participant or other entity through which their Shares are held) to transfer the Shares. Transfers are made in accordance with standard securities industry practice.

Employees

The Funds have no employees. Management functions are performed by the Managing Owner and requisite administrative services are provided on a contractual basis by various entities.

Conflicts of Interest

General

Investors are dependent on the good faith of the respective parties subject to such conflicts to resolve them equitably. Although the Managing Owner attempts to monitor these conflicts, it is extremely difficult, if not impossible, for the Managing Owner to ensure that these conflicts do not, in fact, result in adverse consequences to the Fund.

The Managing Owner andSub-Adviser

The Managing Owner andSub-Adviser each have a conflict of interest in allocating its own limited resources among different clients and potential future business ventures, to each of which it owes fiduciary duties.

Additionally, the directors, officers and/or employees of the Managing Owner andSub-Adviser also service other affiliates of such parties and their respective clients. Although the Managing Owner andSub-Adviser and their directors, officers and/or employees cannot and will not devote all of its or their respective time or resources to the management of the business and affairs of the Funds, such parties intend to devote, and to cause its directors, officers and employees to devote, sufficient time and resources to properly manage the business and affairs of the Funds consistent with its or their respective duties to the Funds and others.

The Commodity Broker

The Commodity Broker may act from time to time as a broker for other accounts with which it is affiliated or in which it or one of its affiliates has a financial interest. The compensation received by the Commodity Broker from such accounts may be more or less than the compensation received for brokerage services provided to the Master Fund. In addition, various accounts traded through the Commodity Broker (and over which their personnel may have discretionary trading authority) may take positions in the futures markets opposite to those of the Master Fund or may compete with the Master Fund for the same positions. The Commodity Broker may have a conflict of interest in its execution of trades for the Master Fund and for other customers. The Managing Owner, under delegation to theSub-Adviser, does not presently intend to retain any commodity broker for the Master Fund which theSub-Adviser has reason to believe would knowingly or deliberately favor any other customer over the Master Fund with respect to the execution of commodity trades.

The Commodity Broker will benefit from executing orders for other clients, whereas the Master Fund may be harmed to the extent that the Commodity Broker has fewer resources to allocate to the Master Fund’s accounts due to the existence of such other clients.

Certain officers or employees of the Commodity Broker may be members of U.S. commodities exchanges and/or serve on the governing bodies and standing committees of such exchanges, their clearing houses and/or various other industry organizations. In such capacities, these officers or employees may have a fiduciary duty to the exchanges, their clearing houses and/or such various other industry organizations which could compel such employees to act in the best interests of these entities, perhaps to the detriment of the Master Fund.

Proprietary Trading/Other Clients

The Managing Owner, theSub-Adviser and the Commodity Broker and their respective principals and affiliates may trade in the commodity markets for their own accounts and for the accounts of their clients, and in doing so may take positions opposite to those held by the Master Fund or may compete with the Master Fund for positions in the marketplace. Such trading may create conflicts of interest on behalf of one or more such persons in respect of their obligations to the Master Fund. Records of proprietary trading and trading on behalf of other clients will not be available for inspection by Shareholders.

Because the Managing Owner, theSub-Adviser and the Commodity Broker and their respective principals and affiliates may trade for their own accounts at the same time that they are managing the account of the Master Fund, prospective investors should be aware that — as a result of a neutral allocation system, testing a new trading system, trading their proprietary accounts more aggressively or other activities not constituting a breach of fiduciary duty — such persons may from time to time take positions in their proprietary accounts which are opposite, or ahead of, the positions taken for the Master Fund.

No Distributions

The Managing Owner has discretionary authority over all distributions made by the Fund. In view of the Fund’s objective of seeking significant capital appreciation, the Managing Owner currently does not intend to make any distributions, but, has the sole discretion to do so from time to time. Greater Management Fees will be generated to the benefit of the Managing Owner if the Fund’s assets are not reduced by distributions to the Shareholders.

Related Party Transactions

There are no material transactions or arrangements between the Funds and any person affiliated with a person providing services to the Funds that require disclosure.

These risk factors should be read in connection with the other information included in this Annual Report, including Management’s Discussion and Analysis of Financial Condition and Results of Operations and the Funds’ Financial Statements and the related Notes to the Funds’ Financial Statements.

The value of the Shares relates directly to the value of the Master Fund’s Portfolio.

The Shares are designed to reflect, as closely as possible, the performance of the Index through the Master Fund’s Portfolio of exchange-traded Commodity Futures on the Index Commodities. Accordingly, the value of the Shares relate directly to the value of the Portfolio, less the Funds’ liabilities (including estimated accrued but unpaid expenses). The markets and prices of the Index Commodities may fluctuate widely based on many factors, including:

In addition to the factors set forth above, each commodity has risks that are inherent in the investment in such commodity.

Metals Commodities: Price movements in Commodity Futures held by the Master Fund in metals commodities such as gold, silver, platinum and copper are affected by many specific other factors. Some of these metal specific factors include, but are not limited to:

Agricultural Commodities: Price movements in Commodity Futures held by the Master Fund in agricultural commodities, such as wheat, corn and soybeans, are affected by many factors. Some of these agricultural specific factors include, but are not limited to:

Energy Commodities: Price movements in Commodity Futures held by the Master Fund in energy commodities, such as crude oil, heating oil and natural gas, are subject to risks due to frequent and often substantial fluctuations in energy commodity prices. In the past, the prices of natural gas and crude oil have been extremely volatile, and the Managing Owner expects this volatility to continue. The markets and prices for energy commodities are affected by many factors. Some of those factors include, but are not limited to:

None of these factors can be controlled by the Managing Owneror Sub-Adviser. Even if current and correct information as to substantially all factors are known or thought to be known, prices still will not always react as predicted. The profitability of the Fund and the Master Fund will depend on whether the Master Fund’s Portfolio increases in value over time. If the value increases, the Fund will only be profitable if such increases exceed the fees and expenses of the Funds. If these values do not increase, the Fund will not be profitable and will incur losses.

Net Asset Value may not always correspond to the market price of the Shares.

The Net Asset Value will change as fluctuations occur in the market value of the Master Fund’s Portfolio. Investors should be aware that the public trading price of a Basket of Shares may be different from the Net Asset Value per Basket of Shares (i.e., Shares may trade at a premium over, or a discount to, the Net Asset Value per Basket of Shares) and similarly the public trading market price per Share may be different from the Net Asset Value per Share. Consequently, an Authorized Participant may be able to create or redeem a Basket of Shares at a discount or a premium to Net Asset Value. This price difference may be due, in large part, to the fact that supply and demand forces are at work in the secondary trading market for Shares that is closely related to, but not identical to, the same forces

influencing the prices of the Index Commodities trading individually or in the aggregate at any point in time. Investors also should note that the size of the Fund in terms of total assets held may change substantially over time and from time to time as Baskets are created and redeemed.

Authorized Participants or their clients or customers may have an opportunity to realize a profit if they can purchase a Basket at a discount to the public trading price of the Shares or can redeem a Basket at a premium over the public trading price of the Shares. The Managing Owner expects that the exploitation of such arbitrage opportunities by Authorized Participants and their clients and customers will tend to cause the public trading price to not materially differ from the Net Asset Value per Share over time.

If the Fund issues all of its registered Shares, it could have to cease creating new Baskets until additional shares are registered for sale.

Investors should be aware that if the Fund issues all of its registered Shares, it could have to cease creating new Baskets until additional shares are registered for sale. This could increase the possibility that the trading price of the Fund’s Shares may not accurately reflect the Index or the Net Asset Value of the Fund. As of December 31, 2017,2018, there were 60,450,00057,700,000 Shares available for issuance.

Moreover, soon after new Baskets are created and sold, there is a possibility that the availability of newly created Shares may (or may not) affect the trading price of the Shares already issued, and both current Shareholders and purchasers of newly created Shares could be adversely affected by falling trading prices.

The License Agreement between the Index Sponsor and the Managing Owner could terminate.

The Index Sponsor entered into a license agreement with the Managing Owner whereby the Managing Owner was granted an exclusive license with respect to the development and creation of certain investment products, including U.S. exchange traded funds. The current license granted to the Managing Owner has a term ending December 31, 2020, which will automatically renew for an additional two years and will renew for successive two year terms thereafter. The term may be terminated under certain circumstances which could cause an investment in the Shares to decline significantly in value. In addition, a different product could be created under the license agreement, which could also cause an investment in the Shares to decline in value. If the license expires and is not renewed or is terminated, or a competitive product is created, then the Managing Owner may seek Shareholder approval to the extent required to either (i) liquidate the Funds or (ii) approve a different index for the Master Fund to track.

The Index Sponsor could change the Index or experience system failures.

The Index Sponsor has the right to make adjustments to the Index without regard to the particular interests of the Funds or the Shareholders. In addition, if the computers or other facilities of the Index Sponsor or any Index calculation agent, data providers and/or relevant stock exchange malfunction for any reason, calculation and dissemination of Index values may be delayed and trading in the Shares may be suspended for a period of time. Errors in Index data, Index computations and/or the construction of the Index may occur from time to time and may not be identified and/or corrected by the Index Sponsor for a period of time or at all, which may have an adverse impact on the Fund and the Shareholders. Any of the foregoing may lead to the errors in the Index, which may lead to a different investment outcome than would have been the case had such events not occurred. The Managing Owner, throughthe Sub-Adviser, seeks to manage the Funds to correspond to the Index provided by the Index Sponsor. Consequently, losses or costs associated with the Index’s errors or other risks described above will generally be borne by the Funds and the Shareholders and neither the Managing Owner nor its affiliates or agents make any representations or warranties regarding the foregoing.

Regulatory and exchange position limits and other rules may restrict the creation of Baskets and the operation of the Master Fund.

CFTC and commodity exchange rules impose speculative position limits on market participants, including the Master Fund, trading in certain agricultural commodities. These position limits prohibit any person from holding a position of more than a specific number of such futures contracts. The Managing Owner anticipates that these position limits as well as accountability limits currently in place on

exchanges will impact the Master Fund when the Net Asset Value approaches $1.2 billion, at which point the Managing Owner may either prevent the creation of additional Baskets or apply to the CFTC for relief from certain position limits.

If the Master Fund applies and is unable to obtain such relief, the Fund’s ability to issue new Baskets, or the Master Fund’s ability to reinvest income in additional Commodity Futures, may be limited to the extent these activities would cause the Master Fund to exceed applicable position limits. Limiting the size of the Fund may result in Shares trading at a premium or discount to the Net Asset Value.

The Fund may not always be able exactly to replicate the performance of the Index.

It is possible that the Fund may not fully replicate the performance of the Index due to disruptions in the markets for the Index Commodities or due to other extraordinary circumstances, including, without limitation, the inability to create additional Baskets. In addition, the Fund is not able to replicate exactly the performance of the Index because the total return generated by the Master Fund is reduced by expenses and transaction costs, including those incurred in connection with the Master Fund’s trading activities, and increased by interest income from the Master Fund’s holdings of U.S. Treasuries. Tracking the Index requires rebalancing of the Master Fund’s Portfolio and is dependent upon the skills ofthe Sub-Adviser and its trading principals, among other factors.

The Managing Owner may permit the Master Fund to control commodity positions in excess of the value of the Master Fund’s assets.

Commodity pools’ trading positions in Commodity Futures or other commodity interests are typically required to be secured by the deposit of margin funds that represent only a small percentage of a Commodity Future’s (or other commodity interests’) entire market value. This feature permits commodity pools to increase their exposure to assets by purchasing or selling Commodity Futures (or other commodity interests) with an aggregate value in excess of the commodity pool’s assets. While these actions can increase the pool’s profits, relatively small adverse movements in the price of the pool’s Commodity Futures can cause significant or complete losses to the pool. Whilethe Sub-Adviser is not expected to have exposure to Commodity Futures in excess of the Master Fund’s collateral, the Funds are dependent upon the trading and management skills ofthe Sub-Adviser to maintain the proper position sizes.

The Master Fund is not actively managed and will track the Index during periods in which the Index is flat or declining as well as when the Index is rising.

The Master Fund is not actively managed by traditional methods. Therefore, if positions in any one or more of the Index Commodities are declining in value, the Master Fund will not close out such positions, except in connection with a change in the composition or weighting of the Index.The Sub-Adviser will seek to cause the Net Asset Value to track the Index during periods in which the Index is flat or declining as well as when the Index is rising.

The NYSE Arca may halt trading in the Shares.

The Shares are listed for trading on NYSE Arca under the market symbol “GCC.” Trading in Shares may be halted due to market conditions or, in light of NYSE Arca rules and procedures, for reasons that, in the view of NYSE Arca, make trading in Shares inadvisable. In addition, trading is subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules that require trading to be halted for a specified period based on a specified market decline in the equity markets. There can be no assurance that the requirements necessary to maintain the listing of the Shares will continue to be met or will remain unchanged. The Funds will be terminated if the Shares are delisted.

There can be no guarantee that an active trading market for the Shares will be maintained.

Although the Shares are listed and traded on the NYSE Arca, there can be no guarantee that an active trading market for the Shares will be maintained. Investors that are successful in trading their Shares at a time when no active market exists will likely receive a lower price than the price received if an active market did exist.

The Funds and their service providers are subject to cyber security risks.

The Funds and their service providers may be susceptible to operational and information security risks resulting from a breach in cyber security, including cyber-attacks. A breach in cyber security, intentional or unintentional, may adversely impact the Funds in many ways, including, but not limited to, disruption of the Funds’ operational capacity, loss of proprietary information, theft or corruption of data maintained online ordigitally, denial-of-service attacks on websites or network resources, and the unauthorized release of confidential information. Cyber-attacks affecting the Funds’ third-party service providers, including the ManagingOwner, Sub-Adviser, Administrator, Distributor, Commodity Broker and other parties, may subject the Funds to many of the same risks associated with direct cyber security breaches and adversely impact the Funds. For instance, cyber-attacks may impact the Funds’ ability to calculate Net Asset Value, cause the release of confidential business information, impede trading, cause the Funds to incur additional compliance costs associated with corrective measures, subject the Funds to regulatory fines or other financial losses, and/or cause reputational damage to the Funds. Cyber security breaches of market makers, Authorized Participants, or the issuers of Commodity Futures in which the Funds invest could also have material adverse consequences on the Funds’ business operations and cause financial losses for the Funds and the Shareholders. While the Funds and their service providers have established business continuity plans and risk management systems designed to address cyber security risks, prevent cyber-attacks and mitigate the impact of cyber security breaches, there are inherent limitations on such plans and systems. In addition, the Funds have no control over the cyber security protections put in place by their service providers or any other third parties whose operations may affect the Funds or the Shareholders.

The Funds and their service providers are subject to certain operational risks.

The Funds and their service providers, including the ManagingOwner, Sub-Adviser, Administrator, Distributor, and Commodity Broker, may experience disruptions that arise from human error, processing and communications errors, counterparty or third-party errors, or technology or systems failures, any of which may have an adverse impact on the Funds. Although the Funds and their service providers seek to mitigate these operational risks through their internal controls and operational risk management processes, these measures may not identify or may be inadequate to address all such risks.

The Shares are a relatively new securities product.

The mechanisms and procedures governing the creation, redemption and offering of the Shares are recently developed securities products. Consequently, there may be unanticipated problems or issues with respect to the mechanics of the operations and the trading of the Shares that could have a material adverse effect on an investment in the Shares. In addition, although the Master Fund is not actively “managed” by traditional methods, unanticipated operational or trading problems or issues may not be solvable by the Managing Owneror Sub-Adviser.

Investors should not rely on past performance in deciding whether to buy Shares.

The Funds’ and the Index’s performance history is not necessarily indicative of future results. Therefore, investors should not rely upon the past performance of the Funds or the Index in deciding whether to buy Shares in the Fund. Further, the past performance of the Funds through December 31, 2015, is a reflection of the performance associated with the prior principals of the Managing Owner (who are now principals ofthe Sub-Adviser) and new principals were installed as a result of the change in ownership of the Managing Owner. Such changes may impact future performance.

Commodity Futures are subject to a high degree of price volatility.

Commodity Futures are subject to a high degree of price variability and therefore may experience rapid and substantial changes in price. These changes cannot be accurately predicted, and could materially and adversely affect the value of the Master Fund’s Portfolio and the Shares.

Fees are charged regardless of profitability.

The Funds are subject to the fees and expenses described in this Annual Report, which are payable irrespective of profitability. Such fees and expenses include asset-based fees of up to 0.85% per annum (which is currently 0.75% per annum after the Managing Owner voluntarily agreed to waive a portion of its Management Fee in the amount of 0.10% per annum) payable to the Manager Owner and brokerage fees equal to approximately 0.10%0.09% per annum based on the Fund’s Net Asset Value as of December 31, 2017.2018. The Managing Owner assumes all routine operational, administrative and other ordinary expenses of the Funds, and will not be reimbursed for any such expenses. The Fund is expected to earn interest income at an annual rate of 1.39%2.45% per annum, based upon the yield on a three month U.S. Treasury bill as of December 31, 2017.2018. Consequently, interest income exceeded the fees and costs incurred by the Funds for the year ended December 31, 2017,2018, however there can be no assurance that this trend will continue. The expenses of the Funds could, over time, increase or the interest income of the Fund could, over time, decrease and the Fund may need to have positive performance in order to break-even (net of fees and expenses). If expenses increase or interest income decreases, these changes could result in significant losses to an investment in the Shares and a Shareholder may never achieve profits, significant or otherwise.

Possible illiquid markets may exacerbate losses.

Futures 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, such as when foreign governments may take or be subject to political actions which disrupt the markets in their currency or major exports, can also make it difficult to liquidate a position. Such periods of illiquidity and the events that trigger them are difficult to predict and there can be no assurance that the Managing Owneror Sub-Adviser will be able to do so.

There can be no assurance that market illiquidity will not cause losses for the Fund. The large size of the positions which the Master Fund may acquire on behalf of the Fund increases the risk of illiquidity by both making its positions more difficult to liquidate and increasing the losses incurred while trying to do so.

Redemption orders may be postponed, suspended or rejected under certain circumstances.

The Managing Owner may suspend the right of redemption or postpone the redemption settlement date (1) for any period during which an emergency exists as a result of which the redemption distribution is not reasonably practicable, or (2) for such other period as the Managing Owner determines to be necessary for the protection of the Shareholders. In addition, the Administrator will reject a redemption order if the order is not in proper form as described in the Participant Agreement or if the fulfillment of the order, in the opinion of its counsel, might be unlawful. Any such postponement, suspension or rejection could adversely affect the redemption of a Basket. For example, the resulting delay may adversely affect the value of the Authorized Participant’s redemption proceeds if the Net Asset Value of the Fund declines during the period of the delay. The Funds, the Administrator, the Managing Owner andtheSub-Adviser disclaim disclaim any liability for any loss or damage that may result from any such suspension or postponement.

The positive performance of the Master Fund’s Portfolio is wholly dependent upon an equal and offsetting loss borne by unrelated participants in the futures markets.

Futures trading is a risk transfer economic activity. For every gain there is an equal and offsetting loss rather than an opportunity to participate over time in general economic growth. Unlike most alternative investments, an investment in Shares does not involve acquiring any asset with intrinsic value. Overall stock and bond prices could rise significantly and the economy as a whole prosper while the Shares may trade unprofitably.

Shareholders will not have the protections associated with ownership of shares in an investment company registered under the Investment Company Act of 1940.

Neither the Fund nor the Master Fund is registered as an investment company under the Investment Company Act of 1940 and is not required to register under such act. Consequently, Shareholders will not have the regulatory protections provided to investors in investment companies.

Various actual and potential conflicts of interest may be detrimental to Shareholders.

The Funds are subject to actual and potential conflicts of interest involving the ManagingOwner, Sub-Adviser, various commodity futures brokers and Authorized Participants. The Managing Owner,the Sub-Adviser and their respective principals, all of which are engaged in other investment or related activities, are not required to devote substantially all of their time to the business of the Funds, which also presents the potential for numerous conflicts of interest with the Funds. As a result of these and other relationships, parties involved with the Funds have a financial incentive to act in a manner other than in the best interests of the Funds and the Shareholders. Investors will be dependent on the good faith of the respective parties subject to such conflicts to resolve them equitably. Although the respective parties attempt to monitor these conflicts, it is extremely difficult, if not impossible, for such parties to ensure that these conflicts do not, in fact, result in adverse consequences to the Shareholders.

In addition, the Fund may be subject to certain conflicts with respect to its Commodity Broker, including, but not limited to, conflicts that result from receiving greater amounts of compensation from other clients, and purchasing opposite or competing positions on behalf of third-party accounts traded through the Commodity Broker.

The Fund’s tax treatment depends onits status asapartnership for federal income tax purposes,,as well as not being subject to a material amount of entity-level taxation by individual states.states. If theInternal Revenue Service(“IRS”)were to treatthe Fundas a corporation for federal income tax purposesorthe Fund becomes becomes subject to material additional amounts of entity-level taxation for state tax purposes,, thenthe amount of cash available for distribution would be substantially reduced.

The anticipatedafter-tax economic benefit of an investment in the Shares depends largely on the Funds being treated as partnerships for federal income tax purposes. No ruling from the IRS on this or any other tax matter affecting the Funds has been requested.

It is possible in certain circumstances an entity that would otherwise be classified as a partnership for U.S. federal income tax purposes, such as the Fund, to be treated as an association or a publicly traded partnership (that does not satisfy the exception set forth in Code Section 7704(c)) taxable as a corporation for U.S. federal income tax purposes. Although the Fund is not believed to be so treated based upon current operations, a change in the Fund’s business or a change in current law could cause the Fund to be treated as a corporation for federal income tax purposes or otherwise subject to taxation as an entity.

If the Fund was treated as a corporation for federal income tax purposes, it would pay federal income tax on taxable income at the corporate tax rate, and would likely pay state and local income tax at varying rates. Distributions would generally be taxed again as corporate dividends (to the extent of the Fund’s current and accumulated earnings and profits), and no income, gains, losses, deductions or credits would flow through to the Shareholders. Because a tax would be imposed upon the Fund as a corporation, the amount of cash available for distribution would be substantially reduced. Therefore, if the Fund was treated as a corporation for federal income tax purposes, there would be a material reduction in the anticipated cash flow andafter-tax return to the Shareholders, likely causing a substantial reduction in the value of the Shares.

At the state level, several states are evaluating ways to subject partnerships to entity-level taxation through the imposition of state income, franchise and other forms of taxation. Imposition of such a tax on the Fund by any state will reduce the cash available for distributions to the Shareholders.

Recently enacted U.S. tax legislation, as well as potential legislative, judicial or administrative changes or differing interpretations, may have an adverse impact on the Fund and Shareholders.

On December 22, 2017, Public LawNo. 115-97, informally titled the Tax Cuts and Jobs Act (the “Tax Act”), was enacted. The Tax Act significantly changed the U.S. Internal Revenue Code of 1986, as amended (the “Code”), including by (i) introducing a new deduction on certain pass-through income, (ii) repealing the partnership technical termination rule, and (iii) imposing a new limitation on the deductibility of interest expense.

The Tax Act will bebecame fully effective in the 2018 fiscal year. The Tax Act is complex and its ultimate impact may differ from this description due to changes in interpretations, as well as additional regulatory guidance that may be issued. Apart from enactment of the Tax Act, tax laws and interpretations thereof are subject to change, possibly on a retroactive basis, and other legislative proposals or administrative or judicial developments could also result in an increase in the amount of U.S. tax payable by the Fund or by Shareholders.

Shareholders will be subject to taxation on their share of the Fund’s taxable income, whether or not they receive cash distributions.

Shareholders will be subject to U.S. federal income taxation and, in some cases, state, local, or foreign income taxation on their share of the Fund’s taxable income, whether or not they receive cash distributions from the Fund. Shareholders may not receive cash distributions equal to their share of the Fund’s taxable income or even the tax liability that results from such income.

Items of income, gain, deduction, loss and credit with respect to the Shares could be reallocated if the IRS does not accept the assumptions or conventions used by the Funds in allocating either Fund’s tax items.

U.S. federal income tax rules applicable to partnerships are complex and often difficult to apply to publicly traded partnerships. The Funds will apply certain assumptions and conventions in an attempt to comply with applicable rules and to report income, gain, deduction, loss and credit to the Shareholders in a manner that reflects the Shareholders’ beneficial shares of partnership items, but these assumptions and conventions may not be in compliance with all aspects of applicable tax requirements. It is possible that the IRS will successfully assert that the conventions and assumptions used by the Funds do not satisfy the requirements of the Code, and/or the Treasury Regulations promulgated thereunder and could require that items of income, gain, deduction, loss or credit be adjusted or reallocated in a manner that adversely affects Shareholders.

If the IRS contests the U.S. federal income tax positions the Fund takes, the market for the Shares may be adversely impacted and the cost of any IRS contest will reduce the amount of cash available for distribution to the Shareholders.

No ruling from the IRS with respect to the Fund’s treatment as a partnership for U.S. federal income tax purposes or any other matter has been requested. The IRS may adopt positions that differ from the positions the Fund takes, and the IRS’s positions may ultimately be sustained. It may be necessary to resort to administrative or court proceedings to sustain some or all of the positions the Fund takes. A court may not agree with some or all of the positions the Fund takes. Any contest with the IRS, and the outcome of any IRS contest, may have a materially adverse impact on the market for the Shares and the price at which they trade. In addition, the costs of any contest with the IRS will be borne indirectly by the Shareholders because the costs will reduce the amount of cash available for distribution.

Tax gain or loss on the disposition of Shares could be more or less than expected.

If Shareholders sell Shares, they will recognize a gain or loss for federal income tax purposes equal to the difference between the amount realized and their tax basis in those Shares. Because distributions in excess of their allocable share of net taxable income decrease their tax basis in their Shares, the amount, if any, of such prior excess distributions with respect to the Shares a Shareholder sells will, in effect, become taxable income to the Shareholder if it sells such Shares at a price greater than its tax basis in those Shares, even if the price received is less than its original cost. In addition, because the amount realized includes a Shareholder’s share of nonrecourse liabilities, a Shareholder that sells common units may incur a tax liability in excess of the amount of cash received from the sale.

New rules regarding U.S. federal income tax liability arising from IRS audits could adversely affect Shareholders.

For tax years beginning after December 31, 2017, ifIf the IRS makes audit adjustments to the FundsFunds’ income tax returns, itthe IRS (and some states) may assess and collect any taxes (including any applicable penalties and interest) resulting from such audit adjustments directly from the Fund. To the extent possible under the new rules, the Managing Owner may elect to either pay the taxes (including any applicable penalties and interest) directly to the IRS or, if the Fund is eligible, issue a revised information statement to each Shareholder and former Shareholder with respect to an audited and adjusted return. Although the Managing Owner may elect to have Shareholders and former Shareholders take such audit adjustment into account and pay any resulting taxes (including applicable penalties or interest) in accordance with their interests in the Fund during the tax year under audit, there can be no assurance that such election will be practical, permissible or effective in all circumstances. As a result, current Shareholders may bear some or all of the tax liability resulting from such audit adjustment, even if such Shareholders did not own Shares during the tax year under audit. If, as a result of any such audit adjustment, the Fund is required to make payments of taxes, penalties and interest, the amount of cash available for distribution to Shareholders might be reduced.

Tax-exempt entities face unique tax issues from owning Shares that may result in adverse tax consequences to them.

Investment in the Shares bytax-exempt entities, such as employee benefit plans and individual retirement accounts (known as IRAs) raises issues unique to them. For example, some or all of the Fund’s income allocated to organizations that are exempt from U.S. federal income tax, including IRAs and other retirement plans, may be unrelated business taxable income that is taxable to them.Tax-exempt entities should consult a tax advisor before investing in the Shares.

Non-U.S. Shareholders may be subject to U.S. taxes and withholding with respect to their income and gain from owning Shares.

Non-U.S. Shareholders are generally required to file U.S. income tax returns and pay tax on income effectively connected with a U.S. trade or business. Income allocated to Shareholders and any gain from the sale of Shares may be considered to be effectively connected income. As a result, distributions to aNon-U.S. Shareholder may be subject to withholding at the highest applicable effective tax rate and aNon-U.S. Shareholder who sells or otherwise disposes of a Share may also be subject to U.S. federal income tax on the gain realized from the sale or disposition of that Share.

The Tax Act imposes a withholding obligation of 10% of the amount realized upon aNon-U.S. Shareholder’s sale or exchange of an interest in a partnership that is engaged in a U.S. trade or business. However, due to challenges of administering a withholding obligation applicable to open market trading and other complications, the IRS has temporarily suspended the application of this withholding rule to open market transfers of interests in publicly traded partnerships pending promulgation of regulations or other guidance. The Fund believes that it is a publicly traded partnership for purposes of these rules and is eligible for the temporary suspension of these withholding provisions. It is not clear if or when such regulations or other guidance will be issued.

PROSPECTIVE INVESTORS ARE STRONGLY URGED TO CONSULT THEIR OWN TAX ADVISERS AND COUNSEL WITH RESPECT TO THE POSSIBLE TAX CONSEQUENCES TO THEM OF AN INVESTMENT IN ANY SHARES; SUCH TAX CONSEQUENCES MAY DIFFER IN RESPECT OF DIFFERENT INVESTORS.

Failure of lack of segregation of assets may increase losses.

The Commodity Exchange Act requires a clearing broker to segregate all funds received from customers from such broker’s proprietary assets. If a Commodity Broker fails to do so, the assets of the Master Fund might not be fully protected in the event of the Commodity Broker’s bankruptcy. Furthermore, in the event of a Commodity Broker’s bankruptcy, any Master Fund Units could be limited to recovering only a pro rata share of all available funds segregated on behalf of the Commodity Broker’s combined customer accounts, even though certain property specifically traceable to the Master Fund was held by the Commodity Broker. In addition, it is possible that in the event of a clearing broker’s bankruptcy, investors could experience a loss of all of their funds and assets held by the clearing broker.

In the event of a bankruptcy or insolvency of any exchange or clearing house, the Master Fund could experience a loss of the funds deposited through its Commodity Broker as margin with the exchange or clearing house, a loss of any unrealized profits on its open positions on the exchange, and the loss of realized profits on its closed positions on the exchange.

Regulatory changes or actions may alter the nature of an investment in the Fund.

Considerable regulatory attention has been focusedon non-traditional investment pools which are publicly distributed in the U.S.. There is a possibility of future regulatory changes altering, perhaps to a material extent, the nature of an investment in the Fund or the ability of the Fund to continue to implement its investment strategy.

The futures markets are subject to comprehensive statutes, regulations and margin requirements. In addition, the CFTC and the exchanges are authorized to take extraordinary actions in the event of a market emergency, including, for example, the retroactive implementation of speculative position limits or higher margin requirements, the establishment of daily price limits and the suspension of trading. The regulation of futures transactions in the U.S. is a rapidly changing area of law and is subject to modification by government and judicial action. The effect of any future regulatory change on the Fund is impossible to predict, but could be substantial and adverse.

Termination of the Fund may adversely affect a Shareholder’s portfolio.

The Managing Owner may withdraw from the Fund upon one hundred and twenty (120) days’ notice, which would cause the Fund to terminate unless a substitute managing owner is identified and instituted. Shareholders cannot be assured that the Managing Owner will be willing or able to continue to service the Funds for any length of time. In addition, owners of seventy-five percent (75%) of the Shares have the power to terminate the Fund. If the Managing Owner discontinues its activities on behalf of the Funds, or the Shareholders terminate the Fund, an investment in the Shares could be adversely affected.

Shareholders do not have the rights enjoyed by investors in certain other vehicles.

As interests in an investment trust, the Shares have none of the statutory rights normally associated with the ownership of common stock of a corporation (including, for example, the right to bring “oppression” or “derivative” actions). In addition, the Shares have limited voting and distribution rights (for example, Shareholders do not have the right to elect directors and the Fund is not required to pay regular dividends, although the Fund may pay dividends at the discretion of the Managing Owner).

An investment in the Shares may be adversely affected by competition from other methods of investing in commodities.

The Funds compete with other financial vehicles, including other commodity pools, hedge funds, traditional debt and equity securities issued by companies in the commodities industry, other securities backed by or linked to such commodities, and direct investments in the underlying commodities or commodity futures contracts. Market and financial conditions, and other conditions that are beyond the Managing Owner’s control, may make it more attractive to invest in other financial vehicles or to invest in such commodities directly, which could limit the market for the Shares and reduce the liquidity of the Shares.

Competing claims over ownership of intellectual property rights related to the Funds could adversely affect the Funds and an investment in the Shares.

Third parties may allege or assert ownership of intellectual property rights which may be related to the design, structure and operations of the Funds. To the extent any claims of such ownership are brought or any proceedings are instituted to assert such claims, the negotiation, litigation or settlement of such claims, or the ultimate disposition of such claims in a court of law if a suit is brought, may adversely affect the Funds and an investment in the Shares.

The prices of Index Commodities may experience “Backwardation” or “Contango.”

As the Master Fund’s futures contracts near expiration, they are replaced by contracts that have a later expiration. Thus, for example, a contract purchased and held in April 2018 may specify a June 2018 expiration. As that contract nears expiration, it may be replaced by selling the June 2018 contract and purchasing the contract expiring in August 2018. This process is referred to as “rolling.” Historically, the prices of crude oil and heating oil have frequently been higher for contracts with shorter-term expirations than for contracts with longer-term expirations, which is referred to as “backwardation.” In these circumstances, absent other factors, the sale of the June 2018 contract would take place at a price that is higher than the price at which the August 2018 contract is purchased, thereby creating a gain in connection with rolling. While crude oil and heating oil have historically exhibited consistent periods of backwardation, backwardation will likely not exist in these markets at all times. The absence of backwardation in crude oil and heating oil could adversely affect the value of the Index and the Shares.

Conversely, gold, corn, soybeans and wheat historically exhibit “contango” markets rather than backwardation. Contango markets are those in which the prices of contracts are higher in the distant delivery months than in the nearer delivery months due to the costs of long-term storage of a physical commodity prior to delivery or other factors. Although gold, corn, soybeans and wheat have historically exhibited consistent periods of contango, contango will likely not exist in these markets at all times. The persistence of contango in gold, corn, soybeans and wheat could adversely affect the value of the Index and the Shares.

The Funds may be required to indemnify the Trustee or the Managing Owner.

Under the Trust Agreements, the Trustee and the Managing Owner have the right to be indemnified for any liability or expense they incur without negligence or misconduct. Accordingly, the Managing Owner may require the assets of the Funds to be sold in order to cover losses or liability suffered by it or by the Trustee. Any such sale would reduce the Net Asset Value and the value of the Shares.

The Funds are subject to extensive regulatory reporting and compliance.

The Funds are subject to changing regulation of corporate governance and public disclosure that could increase the Funds’ costs and risk of noncompliance.

Because the Shares are publicly traded, the Funds are subject to certain rules and regulations of federal, state and financial market exchange entities charged with the protection of investors and the oversight of companies whose securities are publicly traded. These entities, including the Public Company Accounting Oversight Board, the SEC and NYSE Arca, have in recent years issued new requirements and regulations, most notably the Sarbanes-Oxley Act of 2002. From time to time, since the adoption of the Sarbanes-Oxley Act of 2002, these authorities have continued to develop additional regulations or interpretations of existing regulations. The Funds’ ongoing efforts to comply with these regulations and interpretations have resulted in, and are likely to continue resulting in, increased general and administrative expenses and diversion of management time and attention from revenue-generating activities to compliance activities.

The Funds are responsible for establishing and maintaining adequate internal control over financial reporting. The Funds’ internal control system is designed to provide reasonable assurance to its management regarding the preparation and fair presentation of published financial statements. All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

The Funds have assessed the effectiveness of their internal control over financial reporting as of December 31, 2017.2018. Based on its assessment, the Funds believes that, as of December 31, 2017,2018, their internal control over financial reporting is effective.

The Net Asset Value calculation may be overstated or understated due to the valuation method employed when a settlement price is not available on the date of such calculation.

Calculating the Net Asset Value includes, in part, any unrealized profits or losses on open Commodity Futures. Under normal circumstances, the Net Asset Value reflects the settlement price of open Commodity Futures on the date when the Net Asset Value is being calculated. However, if a Commodity Futures traded on an exchange (both U.S.and non-U.S. exchanges) could not be liquidated on such day (due to the operation of daily limits or other rules of the exchange upon which that position is traded or otherwise), the settlement price on the most recent day on which the position could have been liquidated shall be the basis for determining the market value of such position for such day. In such a situation, there is a risk that the calculation of the Net Asset Value on such day will not accurately reflect the realizable market value of such Commodity Futures. For example, daily limits are generally triggered in the event of a significant change in market price of a Commodity Future. Therefore, as a result of the daily limit, the current settlement price is unavailable. Because the settlement price on the most recent day on which the position could have been liquidated would be used in lieu of the actual settlement price on the date of determination, there is a risk that the resulting calculation of the Net Asset Value could be understated or overstated, perhaps to a significant degree.
