The Shares are listed for trading on the NYSE Arca. Trading in Shares may be halted due to market conditions or in light of certain procedures and safeguards under NYSE Arca rules. 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. If the Fund were no

If one or more Authorized Participants withdraws from participation, it may become more difficult to create or redeem Creation Units, which may reduce the liquidity of the Shares. Such circumstances may be

The impact of the COVID-19 pandemic was extensive in many aspects of society. The outbreak resulted in a significant number of deaths, adversely impacted global commercial activity, and led to significant uncertainty and disruptions in the global economy and financial markets. Many countries reacted by instituting quarantines, prohibitions on travel and the closure of offices, businesses, schools, retail stores and other public venues. Businesses also implemented similar precautionary measures. While restrictions

The Index is composed of two Index Commodities, each of which is subject to position limits imposed by the CFTC (pursuant to the phased-in compliance schedule of the CFTC’s recent rulemaking) and/or the rules of futures exchanges on which Index Contracts are traded. The CFTC amended its position limits rules in October 2020. Pursuant to the amended rules, federal position limits apply to 25 physical delivery commodity futures contracts and options thereon, as well as to swaps that are economically equivalent to such contracts and to futures and options thereon that are directly or indirectly linked to the price of such contracts or to the same commodity underlying such contracts (e.g., cash-settled look-a-like futures). Under the amended framework, position limits (i) for 25 core referenced futures contracts (including corn,

The Commodity Exchange Act requires an FCM to segregate all funds received from customers from such FCM’s proprietary assets. If the Commodity Broker fails to segregate customer assets as required, the assets of the Fund might not be fully protected in the event of the Commodity Broker’s distress, impairment or bankruptcy. Furthermore, in the event of the Commodity Broker’s distress, impairment or bankruptcy, the Fund could be delayed in recovering Fund assets, limited to recovering a pro rata share of

The Managing Owner may, in its discretion, suspend the right of redemption or postpone the redemption order settlement date with respect to Creation Units for (1) any period during which an emergency exists as a result of which the redemption distribution is not reasonably practicable, or (2) such other period as the Managing Owner determines to be necessary for the protection of the Shareholders. In addition, the Fund will reject a redemption order if the order is not in proper form as described in the Participant Agreement with the Authorized Participant, or if the fulfillment of the order, in the opinion of the Fund’s counsel, might be unlawful. Any such postponement, suspension or rejection could adversely affect a redeeming Authorized Participant. For example, the resulting delay may adversely affect the value of the

The principal office of the Managing Owner is located at c/o Invesco Capital Management LLC, 3500 Lacey Road, Suite 700, Downers Grove, IL 60515. The telephone number of the Managing Owner is (800) 983-0903.

The Managing Owner may determine to invest in other futures contracts if at any time it is impractical, including in scenarios wherein the futures market for an Index Contract is thinly traded, or inefficient to gain full or partial exposure to an Index Commodity through the use of Index Contracts or other futures contracts. These other futures contracts may or may not be based on the Index Commodities. When they are not, the Managing Owner may seek to select futures contracts that it reasonably believes tend to exhibit trading prices that correlate with the Index Contract. As the Fund, which is designed to track an Index with more than one underlying commodity, approaches or reaches position limits with respect to an Index Commodity, the Fund may commence investing in Index Contracts that reference other Index Commodities. In those circumstances, the Fund may also trade in futures contracts based on commodities

Creation Units may be created or redeemed only by Authorized Participants. Each Authorized Participant must (1) be a registered broker-dealer or other securities market participant such as a bank or other financial institution which is not required to register as a broker-dealer to engage in securities transactions, (2) be a participant in DTC, and (3) have entered into a Participant Agreement with the Fund and the Managing Owner. The Participant Agreement sets forth the procedures for the creation and redemption of Creation Units and for the delivery of cash required for such creations or redemptions. A list

Because orders to purchase Creation Units must be placed by 10:00 a.m., Eastern time, but the total payment required to create a Creation Unit will not be determined until 4:00 p.m., Eastern time, on the date the creation order is received, Authorized Participants will not know the total amount of the payment required to create a Creation Unit at the time they submit the creation order for the Creation Unit. The Fund’s NAV and the total amount of the payment required to create a Creation Unit could rise or fall

The redemption proceeds due from the Fund are delivered to the Authorized Participant at 2:45 p.m., Eastern time, on the redemption order settlement date if, by such time, the Fund’s DTC account has been credited with the Creation Units to be redeemed. If the Fund’s DTC account has not been credited with all of the Creation Units to be redeemed by such time, the redemption distribution is delivered to the extent of whole Creation Units received. Any remainder of the redemption distribution is delivered on the next business day to the extent of remaining whole Creation Units received if the Transfer Agent receives the

MS&Co. is a wholly-owned, indirect subsidiary of Morgan Stanley, a Delaware holding company. Morgan Stanley files periodic reports with the SEC as required by the Exchange Act, which include current descriptions of material litigation and material proceedings and investigations, if any, by governmental and/or regulatory agencies or self-regulatory organizations concerning Morgan Stanley and its subsidiaries, including MS&Co. As a consolidated subsidiary of Morgan Stanley, MS&Co. does not file its own periodic reports with the SEC that contain descriptions of material litigation, proceedings and

On July 15, 2010, China Development Industrial Bank (“CDIB”) filed a complaint against MS&Co., styled China Development Industrial Bank v. Morgan Stanley & Co. Incorporated et al., which is pending in the Supreme Court of the State of New York, New York County (“Supreme Court of NY”). The complaint relates to a $275 million credit default swap referencing the super senior portion of the STACK 2006-1 CDO. The complaint asserts claims for common law fraud, fraudulent inducement and fraudulent concealment and alleges that MS&Co. misrepresented the risks of the STACK 2006-1 CDO to CDIB, and that MS&Co. knew that the assets backing the CDO were of poor quality when it entered into the credit default swap with CDIB. The complaint seeks compensatory damages related to the approximately $228 million that CDIB alleges it has already lost under the credit default swap, rescission of CDIB’s obligation to pay an additional $12 million, punitive damages, equitable relief, fees and costs. On February 28, 2011, the court denied MS&Co.’s motion to dismiss the complaint. On December 21, 2018, the court denied MS&Co.’s motion for summary judgement and granted in part MS&Co.’s motion for sanctions related to the spoliation of

On May 17, 2013, a plaintiff in IKB International S.A. in Liquidation, et al. v. Morgan Stanley, et al. filed a complaint against MS&Co. and certain affiliates in the Supreme Court of NY. The complaint alleges that the defendants made material misrepresentations and omissions in the sale to the plaintiff of certain mortgage pass-through certificates backed by securitization trusts containing residential mortgage loans. The total amount of certificates allegedly sponsored, underwritten and/or sold by MS&Co. to the plaintiff was approximately $133 million. The complaint alleges causes of action against MS&Co. for common law fraud, fraudulent concealment, aiding and abetting fraud, and negligent misrepresentation, and seeks, among other things, compensatory and punitive damages. On October 29, 2014, the court granted in part and denied in part MS&Co.’s motion to dismiss. All claims regarding four certificates were dismissed. After these dismissals, the remaining amount of certificates allegedly issued by MS&Co. or sold to the plaintiff by MS&Co. was approximately $116 million. On August 26, 2015, MS&Co. perfected its appeal from the court’s October 29, 2014 decision. On August 11, 2016, the Appellate Division, First Department affirmed the trial court’s decision denying in part MS&Co.’s motion to dismiss the complaint. At June 25, 2018, the current unpaid balance of the mortgage pass-through certificates at issue in this action was approximately $24 million, and the certificates had incurred actual losses of $58 million. Based on currently available information, MS&Co. believes it could incur a loss in this action up to the difference between the $24 million unpaid balance of these certificates (plus any losses incurred) and their fair market value at the time of a judgment against MS&Co., or upon sale, plus pre- and post-judgment interest, fees and costs. MS&Co. may be entitled to be indemnified for some of these losses and to an offset for interest received by the plaintiff prior to a judgment. On July 15, 2022, MS&Co. filed a motion for summary judgment on all remaining claims. On March 1, 2023, the court granted in part and denied in part MS&Co.’s motion for

On December 30, 2013, Wilmington Trust Company, in its capacity as trustee for Morgan Stanley Mortgage Loan Trust 2007-12, filed a complaint against MS&Co. styled Wilmington Trust Company v.

The Managing Owner has not established formal procedures to resolve all potential conflicts of interest. Consequently, investors may be dependent on the good faith of the respective parties subject to such

The Commodity Broker may have a conflict of interest in its execution of trades for the Fund and for other customers. For example, the Commodity Broker may act from time to time as a commodity 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 Fund. Customers of the Commodity Broker who maintain commodity trading accounts may pay commissions at negotiated rates which are greater or

The Trust was formed and is operated in a manner such that each Fund is liable only for obligations attributable to that Fund and the Shareholders of a Fund are not subject to the losses or liabilities of any of

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 in accordance with the Managing Owner’s instructions. The Shareholders have no voice in the day-to-day management of the business and operations of the Trust and the Fund, other than certain limited voting rights as set forth in

The Trust Agreement permits the approval of actions through the negative consent of Shareholders. As provided in the Trust Agreement, the vote or consent of each Shareholder so solicited will be deemed conclusively to have been cast or granted as requested in the notice of solicitation, whether or not the notice of solicitation is actually received by that Shareholder, unless the Shareholder expresses written objection to the vote or consent by notice given in the manner provided in the Trust Agreement and actually received by the Trust within twenty (20) days after the notice of solicitation is effected. Because the Trust Agreement provides for negative consent (e.g., that Shareholders are deemed to have consented

Individual certificates will not be 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 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

The Administrator retains, separately for the Fund, certain financial books and records, including: Fund accounting records, ledgers with respect to assets, liabilities, capital, income and expenses, the registrar, transfer journals and related details and trading and related documents received from FCMs, c/o The Bank of New York Mellon, 240 Greenwich Street, New York, New York 10007, telephone number (718) 315-7500.

Both the Managing Owner and DBSI have the right to terminate on notice subject to payment of a termination fee, both with respect to a given fund and with respect to all funds subject to these agreements. Each party also has the right to terminate for cause, although the Managing Owner’s ability to exercise this right is restricted to a narrow set of circumstances during the initial one-year term. Accordingly, there may be circumstances where the Managing Owner would otherwise believe cause

Notwithstanding any other provision contained in the Administration Agreement, the Administrator will have no duty or obligation with respect to, including, without limitation, any duty or obligation to determine, or advise or notify the Fund of: (a) the taxable nature of any distribution or amount received or deemed received by, or payable to the Fund; (b) the taxable nature or effect on the Fund or its shareholders of any corporate actions, class actions, tax reclaims, tax refunds, or similar events; (c) the taxable nature or taxable amount of any distribution or dividend paid, payable or deemed paid by the

Under the monthly allocation convention, whoever is treated for U.S. federal income tax purposes as holding Shares as of the close of the last trading day of the preceding month will be treated as continuing to hold the Shares until immediately before the close of the last trading day of the following month. With

The Fund has made the election permitted by Section 754 of the Code. Such an election, once made, is irrevocable without the consent of the IRS. The making of the Section 754 election by the Fund will generally have the effect of requiring a purchaser of Shares to adjust its proportionate share of the basis in

If a U.S. Shareholder transfers Shares and such transfer is a sale or other taxable disposition, the U.S. Shareholder will generally be required to recognize gain or loss measured by the difference between the amount realized on the sale and the U.S. Shareholder’s adjusted tax basis in the Shares sold. The amount realized will include an amount equal to the U.S. Shareholder’s share of the Fund’s liabilities, as well as any proceeds from the sale. The gain or loss recognized will generally be taxable as capital gain or loss. Capital gain of non-corporate U.S. Shareholders is eligible to be taxed at reduced rates where the Shares sold are considered held for more than one year. Capital gain of corporate U.S. Shareholders is taxed at the same rate as ordinary income. Any capital loss recognized by a U.S. Shareholder on a sale of Shares will generally

The Fund intends to conduct its activities in such a manner that a non-U.S. Shareholder who is not otherwise carrying on a trade or business in the United States is not expected to be considered to be engaged in a trade or business in the United States as a result of an investment in the Shares. A non-U.S. Shareholder’s share of the interest income realized by the Fund on its holdings of Treasury Securities will be exempt from U.S. withholding tax provided the non-U.S. Shareholder certifies on IRS Form W-8BEN or IRS Form W-8BEN-E (or other applicable form) that the Shareholder is not a U.S. person, provides name and address information and otherwise satisfies applicable documentation and certification requirements. In addition, with respect to certain distributions made to non-U.S. Shareholders, no withholding is required and the distributions by the Fund that relate to dividends paid to the Fund by money market

The Fund anticipates that it will qualify as a qualified PTP for any taxable year in which the Fund realizes sufficient gross income from its commodity futures transactions. However, qualification of the Fund as a qualified PTP depends on performance of the Fund for the particular tax year and there is no assurance that it will qualify in a given year or that future results of the Fund will conform to prior experience. In

State and local tax laws often differ from U.S. federal income tax laws with respect to the treatment of specific items of income, gain, loss, deduction and credit for state net income tax purposes. For Shareholders that are taxed as entities for state or local tax income tax purposes, the taxable nexus, income, and apportionment factors of the Fund may flow through to the Shareholder and such flow-through may disproportionately impact the taxability of the Shareholder in one or more jurisdictions relative to that Shareholder’s distributive share from the Fund. For Shareholders that are individuals, the taxable nexus and apportioned income of the Fund will generally flow through to the Shareholder and the Shareholder’s distributive share of the taxable income or loss of the Fund generally will be required to be

The Foreign Account Tax Compliance Act provisions of the Hiring Incentives to Restore Employment Act (“FATCA”) generally impose a reporting and 30% withholding tax regime with respect to certain items of U.S. source income (including dividends and interest) (“Withholdable Payments”). While the 30% withholding tax would have applied also to payments of gross proceeds from the sale or other disposition on or after January 1, 2019 of property that would give rise to U.S. source interest or dividends, proposed Treasury Regulations eliminate such withholding on payments of gross proceeds entirely. The U.S. Treasury Department has indicated that taxpayers may rely on these proposed Treasury Regulations

In general, the terms “employee benefit plan” as defined in ERISA and “plan” as defined in Section 4975 of the Code together refer to any plan or account of various types which provide retirement benefits or welfare benefits to an individual or to an employer’s employees and their beneficiaries. Such plans and

Authorized Participants may offer to the public, from time to time, Shares from any Creation Units they create. Shares offered to the public by Authorized Participants will be offered at a per Share offering price that will vary depending on, among other factors, the trading price of the Shares on the NYSE Arca, the NAV per Share and the supply of and demand for the Shares at the time of the offer. Shares initially comprising the same Creation Unit but offered by Authorized Participants to the public at different times may have different offering prices. The excess, if any, of the price at which an Authorized Participant sells a Share over the price paid by such Authorized Participant in connection with the creation of such Share in a Creation Unit may, depending on the facts and circumstances, be deemed to be underwriting compensation by the FINRA Corporate Financing Department. Authorized Participants will not receive from the Fund, the Managing Owner or any of their affiliates, any fee or other compensation in connection with their sale of Shares to the public, although investors are expected to be charged a commission by

Each futures exchange in the United States has an associated “clearing house.” Once trades between members of an exchange have been confirmed, the clearing house becomes substituted for each buyer and each seller of contracts traded on the exchange and, in effect, becomes the other party to each trader’s open position in the market. Thereafter, each party to a trade looks only to the clearing house for
